Extra-Terrestrial Mission:
An extra-terrestrial mission is an exploratory mission beyond Earth and usually involves orbiting, landings, or experiments on a celestial body. The mission involves analyzing scientific data, taking samples, and performing observations of the environment and any possible lifeforms. Such missions often use space probes and robotic spacecrafts to collect data and are aimed at gaining a better understanding of our universe.
